The daily MSW generation is approximately 2,478 tons in Taichung Special Municipality. The average ratios of waste, recycled resources and food waste are about 63%, 28% and 9%, respectively [10]. The composites of resource cycling and food waste are shown in Fig.2 (a) and (b), respectively.

(a) (b) Fig.2 Composites of resource cycling and food waste [10] The MSW treatment costs for the 3 incinerators, namely Nantun, Houli and Wurih, are 489, 339 and 129 NT$/ton, respectively, and the treatment cost of general industrial waste is 2,100 NT$/ton for each incinerator. Additionally, according to the contracts between the incinerators and government, the guaranteed MSW quantity supplied by government is 603, 553 and 510 ton/day, respectively [10]. The waste to electricity transfer coefficient (WETC), the selling rate of electricity (SRE), the selling prices (SP), the generated rate of button ashes (GRBA), the generated rate of fly ashes (GRFA) and loading of the 3...
